I tested like this:
auditctl -m `perl -e '{print "A"x"2048"}'`
and found its getting cutoff just under 1K. So, I checked the kernel code and
found this:
761 if (msg_type != AUDIT_USER_TTY)
762 audit_log_format(ab, " msg='%.1024s'",
763 (char *)data);
764 else {
Offhand, I don't remember why the kernel sets the limit so low. It could be
bumped some. How much, I don't know. 4K or 8K would seem fine.
